This study sought to explore low-income father-infant interactions in teach
ing situations. Forty-four biological fathers and infants, recruited from a
n ongoing study of early intervention, were observed using the NCAST Teachi
ng Scale during a teaching task in the home. Results indicated that fathers
who lived with their infants were more sensitive to infant cues during the
interactions. Also, fathers identified as "lower risk," based on a risk in
dex created from demographic characteristics, were more sensitive to their
infants during interactions, had higher total father NCAST scores and highe
r total NCAST scores during teaching interactions.
